atented June 16, 1931 UNITED STATES JOHN W. FRY, OF STRUTHERS, OHIO FLYING MACHINE Application filed March 18, 1830. Serial No. 436,903.

This invention relates to flying machines.

The principal object of this invention is to provide new and improved landing and take-off parts of a flying machine.

Another object of the invention is to provide two landing and take-E wheels, one carried near the front of the machine and the second one carried back of the front wheel and practically directly beneath the center of w gravlty of the machine.

Another object of the device is to provide means for moving these wheels up or down in relation to the plane.

Another object of the device is to mount each of the two wheels upon a pivot-arm, one end of each pivot-arm functioning with a plurality of elastic bands.

A still further object is to provide side support means of a foldable nature, used in 2Q landing and in taking off.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation of a portion of a flying machine showing my improved device installed thereon. I Figure 2 is a side elevation of a flying machine with my improved device attached thereon, showing landing and taking-off wheels in a position for landing.

Figure 3 is a cross section taken on line 3-3 of Figure 1.

Figure 4: is a cross section taken on line H of Figure 2.

By referring to the drawings it will be seen that there is provided an ordinary flying machine 1. This flying machine is provided with a front wheel 2 used for the purpose of landing and taking off, in conjunction with a rear wheel 3, which is also used in landing and taking ofl.

The flying machine 1 is provided at a point 4 with a depended pivot support 5. This pivot support 5 carries a pivot-arm 6. scoured with the pivot support 5 by means of a pivot pin 7. It will be seen that the front end of the pivot-arm 6 carries the front wheel 2. A

rear end 8 of the pivot-arm 6 functions with a plurality of elastic bands 9. These elastic bands 9 are of varying lengths. These elastic bands 9 are secured to a body part of the flying machine 1 at a point 10. This point 10 being at a pivot point of a manipulating lever 11. This manipulating lever 11 is provided with a depended arm 12 which functions with a plurality of elastic bands 13, said elastic bands 13 also functioning with a front end 14 of pivot-arm 15. These elastic bands 13 are of varying lengths. The flying machine which is provided with a rear depended pivot support 16 which carries the pivot-arm 15 by means of a pivot pin 17. The rear end of this pivot-arm 15 carries the rear wheel 3.

Figure 1 shows the wheels 2 and 3 carried in a position when flying machine is in the air. Figure 2 shows the positions of the wheels 2 and 3 when the flying machine is about to land. It will be seen that in the position of the rear wheel 3 when about to land the manipulating lever 11 has been moved forward. This action has caused the rear wheel 3 to be lowered.

When the flying machine reaches the ground, the rear wheel 3 will come in contact with the ground. Due to the plurality of elastic bands 13 and which are of varying lengths. the rear wheel 3 will be forced upward slightly. However in its movement upward added resistance in the upward movement will take place as each of the elastic bands 13 of varying lengths are subjected to tension. In landing the front wheel 2 also comes in contact with the ground and will bcmovedupwardly slightly. This upward movement of the front wheel 2 will meet added resistance as it moves upwardly due to the plurality of elastic bands 9 of varying lengths. It is obvious that as each of the elastic bands 9 are subjected to tension greater resistance in the 100 upward movement of the front wheel 2 will be maintained.

It is believed that the manner of placing the wheels 2 and 3 in relation to the flying machine 1 will be important in preventing a rough landing or a landing where it might otherwise, under ordinary equipment, result in an accident such as the front end of the machine tilting into the ground. It is also obvious that in landing and in taking off by the use of a front wheel and a rear wheel 0- sition underneath the flying machine, the ying machine will not be subjected to the unnecessary shaking and vibrating from side to side which is common in landing or taking off where an ordinary landing gear is used.

In order to prevent tilting of the flying machine 1 when it rests on the ground, or when starting to take oil, or ,when coming to a stop after a landing, it is provided with a pair of support legs 18. These support legs 18 are curved and pivoted at an upper point 19 in order that when not in use they may be folded up as shown in Figure 3. Each of these support legs 18 are provided with a brace member 20 which is pivoted to each support leg 18 by means of a pivot pin 21. It will be seen that the lower end of each support leg 18 is provided with a drag 22. The purpose of these drags 22 is to allow for a forward movement of the flying machine as well as to provide a slidable portion which ma y travel along the ground without setting up undesirable friction.

By referring to Figures 1 and 2 it will be seen that each drag 22 is provided with a tension cable 23 for the purpose of holding the support legs 18 and the drags 22 in an outwardly extended portion best adapted to prevent the flying machine from tilting when at rest or when moving very slowly along the ground.

Having described my invention, what I claim and desire to secure by Letters Patent, 15

1. In a device of the class described, a takeoff and landing portion comprising two wheels positioned directly underneath a center portion of body of flying machine and one wheel directly behind a front wheel, two dependent pivot supports secured to body of said flying machine, a pivot-arm carried on each of said depended pivot-supports, outer ends of each pivot-arm carrying a wheel, inner ends of said pivot-arms functioning with a plurality of elastic bands of uneven lengths, means for raising and lowering rear wheel in relation to the flying machine.

2. In a device of the class described, a landing and taking off portion comprising a front and rear wheel, means for manually raising or lowering said rear wheel, means for allowmg front and rear wheels when coming in contact with a landing field to be forced upwardly toward body of the flying machine yet
